How WiMax Works

... In practical terms, WiMAX would operate similar to WiFi but at higher
speeds, over greater distances and for a greater number of users. WiMAX
could potentially erase the suburban and rural blackout areas that
currently have no broadband Internet access because phone and cable companies have not yet run the necessary wires to those remote locations. ... Link: howstuffworks.com.

Comments

1. Does WiMax requires perfect line of sight and what is the transmitting power?
2. Under non-line of sight for the receiver what will be the power?
3. Does the receiver end will be a PPPoE setup?

1. I do not know the transmitting power, but it does not require perfect line of sight. I use Clearwire's WiMax every day and I am more than 8 kilometers from the transmitter. I have a favorable location on top of a ridge, but there is a small forest blocking the path. The antenna at this end is small and sits in a window.
2. For non-line of sight, the received power will depend on the nature of the obstructions.
3. I do not know the answer to this question, but it appears to be a standard Internet connection.
